Blanket statements don't really make great arguments. That aside, in my experience (webpack for one), projects at scale with JavaScript, are harder to maintain without some type safety and are a bit more bug prone and slower to refactor.
But at the end of the day, its still compiled to JavaScript, whether you chose to slap a .ts file in there, or just use the typechecker standalone is a mere implementation detail.
